DESCRIPTION OF EMBODIMENTS
In order to better understand technical solutions of the present
disclosure, the embodiments of the present disclosure are described
in details with reference to the drawings.
The described embodiments are merely part of the embodiments of the
present disclosure rather than all of the embodiments. All other
embodiments obtained by those skilled in the art without paying
creative labor shall fall into the protection scope of the present
disclosure.
The terms used in the embodiments of the present disclosure are
merely for the purpose of describing particular embodiments and not
intended to limit the present disclosure. Unless otherwise noted in
the context, the singular form expressions "a", "an", "the" and
"said" used in the embodiments and appended claims of the present
disclosure are also intended to represent a plural form.
It should be understood that the term "and/or" as used herein is
merely an association describing the associated object, indicating
that there may be three relationships. For example, A and/or B may
indicate three cases: only A exists; A and B exist concurrently;
only B exists. In addition, a character "/" herein generally
indicates that the contextual objects are in an "or"
relationship.
It should be understood that although the terms first, second, etc.
may be used to describe devices in the embodiments of the present
disclosure, these devices should not be limited to these terms.
These terms are only used to distinguish devices from one another.
For example, a first device could also be termed a second device,
and similarly, a second device could also be termed a first device
without departing from the scope of the embodiments of the present

FIG. 1 illustrates a structural schematic diagram of a touch
display panel 100 in the related art.
As shown in FIG. 1, in the related art, the touch display panel 100
includes a touch driving electrode 110 and a touch sensing
electrode 120. The touch driving electrode 110 includes a touch
driving electrode block 111. The touch sensing electrode 120
includes a touch sensing electrode block 121. In each column of the
touch driving electrode 110, the left side and the right side of
two adjacent touch driving electrode blocks 111 are respectively
provided with one touch sensing electrode block 121. There is
substantially no space in the left side and the right side of the
two adjacent touch driving electrode blocks 111, so that the two
adjacent touch driving electrode blocks 111 cannot be electrically
connected by taking advantages of space on the left side or the
right side. Thus, the pattern design of the touch driving electrode
110 is not flexible.
In order to solve the above technical problems, the present
disclosure provides a touch display panel and a touch display
device.
FIG. 2 illustrates a structural schematic diagram of a touch
display panel 200 according to an embodiment of the present
disclosure.

respectively transmits touch driving signals to each column of the
first touch electrode 210. Each row of the second touch electrode
220 is respectively electrically connected to the touch chip, and
the touch chip respectively detects touch sensing signals of each
row of the second touch electrode 220. The touch chip determines a
touch event according to the touch driving signals and the touch

driving electrode 110, the left and right sides of two adjacent
touch driving electrode blocks 111 are respectively provided with
one touch sensing electrode block 121, and there is substantially
no space in the left and right sides of two adjacent touch driving
electrode blocks 111, such that the two adjacent touch driving
electrode blocks 111 cannot be electrically connected by using the
space on the left or right side. Compared with the related art, in
the embodiment of the present disclosure, in each column of the
first touch electrode 210, two adjacent first electrode blocks 211

one of the first connection lines 212 is smaller than the
resistance of one first connection line 212, and the signal
attenuation between the first one of the first electrode blocks 211

disclosure.
As shown in FIG. 7, the first touch display region 201 is provided
with an opening 250, and the opening 250 is located between two
ends of one row of the second touch electrode 220 that are opposite
in the first direction Y.
In the embodiment of the present disclosure, the first touch
display region 201 is provided with the opening 250. The opening
250 is used to receive one or more of an earpiece, a camera, a
light sensor, a distance sensor, an iris recognition sensor and a
fingerprint recognition sensor. The opening 250 can be a blind hole
or a through hole. The opening 250 in a form of the blind hole

glass cover of the touch display panel 200 can be retained on the
opening 250 in the form of the blind hole, and a touch connection

opening 250 interrupts a single row of the second touch electrode
220, without interrupting multiple rows of the second touch
electrodes 220, such that the effect of the opening 250 on the

end and the lower end of the row of the second touch electrode 220.
The first column of the first touch electrode 210 is located on the
left side, and the second column of the first touch electrode 210
is located on the right side. The opening 250 interrupts the right
end of the first column of the first touch electrode 210 without

electrode 210. The opening 250 interrupts the left end of the
second column of the first touch electrode 210 without interrupting
the right end of the second column of the first touch electrode
210. At the left end of the first column of the first touch
electrode 210, left ends of two adjacent first electrode blocks 211
are electrically connected by the first connection line 212, such

touch connection line 251, and the row of the second touch
electrode 220 where the opening 250 is located is conductive by the
touch connection line 251.
As shown in FIG. 7 and FIG. 8, in one embodiment of the present
disclosure, the opening 250 can be in a form of a blind hole. The
opening 250 in the form of the blind hole penetrates partial film
layers of the touch display panel 200. A glass cover of the touch
display panel 200 can be retained on the opening 250 in the form of
the blind hole, and a touch connection line 251 can be provided on
the glass cover.
In another embodiment of the present disclosure, the opening 250

electrode 220 are electrically connected by the touch connection
line 251, and this row of the second touch electrode 220 is
conductive by the touch connection line 251. The opening 250 is
located in one column of the first touch electrode 210 or between
two adjacent columns of the first touch electrodes 210, and the
opening 250 does not interrupt this column of first touch electrode
210 or these two columns of first touch electrodes 210, such that
this column of the first touch electrode 210 or these two columns
of the first touch electrodes 210 do not need to be conductive by
the touch connection line 251. The opening 250 is provided with one
touch connection line 251, instead of being provided with multiple
touch connection lines 251, thereby preventing crosstalk of the
touch connection lines 251 and improving the signal of the touch
connection line 251.

electrode 220 is conductive by the touch connection line 251. The
resistivity of the touch connection line 251 is greater than the
resistivity of the second connection line 222. A sum of the
resistance of this row of the second touch electrode 220 and the
resistance of the touch connection lines 251 is equal to the
resistance of another row of the second touch electrode 220. The
touch control performance of each row of the second touch electrode
220 is uniform.
